stix2-otf – OpenType Unicode text and maths fonts

The Sci­en­tific and Tech­ni­cal In­for­ma­tion eXchange (STIX) fonts are
in­tended to sat­isfy the de­mand­ing needs of au­thors, pub­lish­ers,
print­ers, and oth­ers work­ing in the sci­en­tific, med­i­cal, and tech­ni­cal
fields.

They com­bine a com­pre­hen­sive Uni­code-based col­lec­tion of
math­e­mat­i­cal sym­bols and al­pha­bets with a set of text faces suit­able
for pro­fes­sional pub­lish­ing.

The fonts are avail­able roy­alty-free un­der the SIL Open Font Li­cense.
